While additive manufacturing provides improvements in realizing designer's functional intent, it still is limited within some additive processes due to necessary residual materials requiring removal. Any additive process using either polymers or metals that requires support structure must subsequently employ means to remove such unwanted support structure. For powder-based processes that support structure is the non-sintered or non-melted materials themselves. In these cases, non-processed materials must be removed post-processing. Figure 1 depicts the challenges found in porous metal (“titanium foam”).
